The cost on the shipping of chemicals is dependent upon the weight of cargo upon loading. You have a choice of purchasing 9,000 gallons of ethanol from Florida or Minnesota. The temperature of the cargo leaving Minnesota is 15.0oC while the temperature of the cargo leaving Florida is 30.5oC. How many pounds are you buying from Minnesota?
Look up the density of ethanol at 15.0oC and 30.5oC. It would make it easier if you found it in lbs/gallon but if not than you must convert. Then
mass = volume x density.
